21008344 S3 Volvo FH16 D16E Clutch Servo Repair Kit

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the critical sealing elements within the clutch actuation system. By replacing worn seals, O-rings, or dust boots, technicians can restore the original performance of the clutch servo at a cost-effective rate. Using high-strength components ensures reliable operation under the demanding conditions of heavy commercial vehicle use.

Compatible vehicles and engines

This specific kit is compatible with Volvo FH series vehicles, including models such as the 400, 420, 440, 460, 480, 500, 520, and 540. It is also designed for use in Volvo FH16 trucks equipped with D16E engines. This ensures precise fitment for heavy-duty vocational applications.

Installation and maintenance

During installation, workshop technicians should verify that the cylinder bore is within service limits and ensure correct seal orientation. It is essential to follow proper lubrication and bleeding procedures to prevent air from entering the hydraulic circuit. If the piston surface shows signs of scoring or excessive wear, a complete servo unit replacement may be more effective.

Troubleshooting and selection

Regular inspection of the clutch servo seals can prevent sudden loss of actuation pressure. Maintaining these components helps ensure smooth gear changes and reduces wear on other drivetrain elements.
